Abstract (en)

[origin: WO2011141033A1] An unbonded flexible pipe having a length and a center axis along its length and comprising an internal sealing sheath around its center axis, a carcass (9) arranged inside the internal sealing sheath, and at least one armor (2-4) arranged around the internal sealing sheath. The carcass (9) comprises at least one helically wound elongate carcass reinforcement element providing a plurality of carcass reinforcement element windings along the length of the pipe wherein the carcass reinforcement element windings surround and/or are surrounded by a polymer structure (5), which polymer structure (5) locks said carcass reinforcement element windings relative to each other. Accordingly the carcass reinforcement element windings need not to be directly interlocked with each other, but are mainly or totally locked to each other by the polymer sturcture (5).
